Description of intervention(s) / exposure
A randomized controlled trial will be employed to investigate the effectiveness of the Mindfulness eHealth program and the Physical Activity eHealth program in comparison to a delayed access (8 weeks) wait control group as a means to increase wellbeing. People visiting the Wellbeing study website, in response to advertisements or through self interest, will be informed of the availability of the study and invited to register their interest. Following completion of the pre-intervention assessments, people taking part in the study will be randomly allocated to one of the three groups above.

The Mindfulness eHealth program consists of three weekly online modules designed to help an individual become more mindful or more aware of moment-to-moment experiences (e.g., thoughts, feelings, images, sensations). The Physical Activity eHealth program consists of three weekly online modules designed to increase physical activity, through increased awareness regarding the benefits, understanding the barriers to physical activity. The online modules from both programs will take approximately 15 minutes to complete each week, as well as some offline activities (e.g., engaging in a brief physical activity, practicing mindfulness). All participants are asked to answer questions about how they are feeling and what they have been doing via the secure website and a mobile app survey form. All participants will also wear the BASIS wrist watch continuously, which is just like a normal watch but it also automatically tracks the number of steps taken and their sleep (e.g., total time asleep, number of interruptions, quality of sleep) over the first 7 weeks of the study. Participants will also receive emails (e.g., when to complete post questionnaires) to help keep them on track.

Participants allocated to the immediate start intervention groups (Mindfulness or Physical Activity eHealth) will complete online questionnaires via a secure website at pre-intervention (Week 0), during-intervention, post-intervention (Week 4), 4 weeks post intervention (Week 8) and at a three month follow-up (Week 16).

The delayed start wait group will be provided access to their choice of either the Physical Activity eHealth or Mindfulness eHealth program following the Week 8 assessment phase. Therefore participants allocated to the delayed start wait group will complete pre-intervention (Week 0), during-wait intervention, post-wait intervention (Week 4), 4 weeks post-wait intervention (Week 8) and a post intervention assessment once they have completed a ehealth program (Week 12).

All participants will also be asked to meet with the researchers on two occasions (Week 0 and Week 8) to undertake three brief computerised cognitive tests (15 minutes), have their resting heart rate variability measured (10 minutes) and to provide a salivary cortisol and blood sample.

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be asked to consent and register their interest online via the Wellness site. Participants will then be contacted and an appointment made to meet with one of the researchers face to face. Following the completion of all of the pre-assessment measures, the participant will be informed about what condition they have been randomly allocated to (and details provided regarding intervention URL address for those receiving immediate access to one of the two eHealth programs). Participants will be randomly allocated using a block design method.

Statistical methods / analysis
Repeated measures ANOVA/multilevel modeling.

Previous research has reported medium effects for the primary measures of interest (depression, anxiety and stress symptoms). Therefore, assuming a small-medium effect (i.e. GPower f(v) test = 0.35), significance set at 5% (p = .05), power at 80%, a sample of 52 will be required to demonstrate statistical significance. However allowing for a 40% attrition rate, we will be required to recruit a total of N = 87 participants or n = 29 in each group.
